Palazzo Spada houses the Council of State since 1927 and was built, not far from Palazzo Farnese, in 1540 by the architect Bartolomeo Baronino, for Cardinal Girolamo Capodiferro (the pontifical treasurer)

 In 1632 it was bought by Cardinal Bernardino Spada upon his return to Rome, who used it as his roman residence. Today the building is the Council of State's headquarters, but a section holds the Spada Gallery. The collection includes paintings by Guido Reni, Carracci, Passarotti, Parmigianino and Solimena. Among its pieces we will admire Andrea del Sarto's "Visitation", Guercino's "Dido's Death", Cardinal Spada's "Portrait" by Guido Reni, two canvases by Atremisia Gentileschi (painted by the artist right before she left Rome) and Borromini's trompe-l'oeil false perspective (baroque illusion) in the arcaded courtyard.

The visit include : Galleria Spada with paintings by Artemisia Gentileschi, Jan Brueghel the Elder, Guido Reni, Guercino.. and, since Palazzo Spada isn't very big, a tour of the Palazzo Farnese district. Entrance to Palazzo Spada 4,00 euro per person The Gallery is open every day except on Mondays.
